Note that "ignored" does not appear as a type of Outcome, because tests are
marked as ignored on the outside and skipped over as the suite executes. So an ignored test never runs, and therefore
never has an outcome. By contrast, a test is determined to be pending by running the test
and observing the actual outcome. If the test body completes abruptly with a TestPendingException,
then the outcome was that the test was pending.
